Serial No. 08,879.

This invention relates to hosiery drying forms and, more particularly, to the provision in such forms of a surface or finish which possesses fabric-retaining properties 5 which will prevent hosiery from creeping on the form during the drying operation.'

Many devices have heretofore been proposed forretaining hosiery properly on a drying form and for keeping the same from creeping during the drying operation. Such devices include fabric engaging clamps of various types and pieces of fabric having an outstanding nap which are secured to the forms and over which the hosiery is drawn. Such devices have, however, not proved entirely successful and particularly in connection'with the drying of the very sheer chiffon hosiery which now constitutes so great a part of the hosiery production in this country.

The purpose of our invention isto overcome the disadvantages and defects of the devices heretofore proposed for preventing the creeping of hosiery on drying forms and the particular object thereof is to provide a surface or finish on the form which will function to retain the hosiery securelyoin place and prevent itscreeping on the form as the fabric sets during the drying operation.

Another object of our invention is to provide a surface or finish on a hosiery drying form which will materially increase the heat radiating properties of the form.

A further object of our invention is to provide a hosiery drying form having a friction surface which will engage and hold the fabric of an article of hosiery placed on the form without snagging the fabric.

Other objects of our invention and the advantages attendant thereon will in part be obvious and in part more fully brought out as the description of the invention proceeds.

7 It will be readily appreciated that an in vention of this character is diflicult to illustrate. Nevertheless, we have appended hereto drawing illustrating a hosiery drying form provided with alfriction surface or finish according to our invention. It will" be understood, however,,that the drawing is illustrative, merely, and that the invention is not limited tothe details of the construction of the form therein disclosed since,

obviously, of modification without departing from the scope of our invention whichresides particularly in the surface of the form.

In the drawing:

Fig. l is a side elevation of a hosiery drying form embodying a surface or finish in accordance with our invention Fig. 2'is a cross section on l1ne,2'-2 of the form is subject to a wide range j Fig. 1 on a considerably enlarged scale and.

greatly exaggeratedfor the purpose of more clearly indicatin thenature of the surface of the form; and

Fig. 3 isa fragmentary sectional view of a portion of the side of the form, greatl'y.70

magnified, and showing particularly the character of the surface thereof.

The hosiery drying form illustrated; in this drawing may be of any well known construction and comprises sides 1, 1, preferably. of steel which are welded or other-. wise secured together along the edges 2 and 3. The exterior surfaceof the sides of the form is indicated by the reference character 4.- and vention lies.

As will be apparent from an inspection of Fig. 3 of the drawing, the surface 4; of our drying form is roughened throughout, the purpose of which, as heretofore stated, is to provide a means for engaging and frictionally holding the fabric of astocking'on the form so that after the stocking has been pulled down upon the form to the proper length it will not creep up during the drymg.

it is in this surfacethat our in-I.s p 0 .ods, ,the ultimate This surface, while it must be sufliciently rough to hold the fabric in place, must not contain sharp projections which would snag the fabric. Thus, the surface a is composed of minute projections and depressions which constitute a friction surface well adapted for our purposes, and may be designated a stippled frictionsurface. This surface may be compared to a half tone engraving, as used in printing, wherein the impression surface is composed of a multitude .of microscopic peaks and depressions and known as a stippled surface.

This particular type of surface'may be produced in any ofa' number of ways. For

example, it maybe etched, or embossed, or

abrasive-blastedsubjected to a blast of granular abrasive material such as sand which is projected under high pressure, or produced by rolling under pressure between rolls that have .a roughened surface. Furthermore, the surface might .be .produced ,by a combination of twoor {more of these meth- .obj ect :being to provide a surface of the requisite roughness which is well adapted to hold the stocking in place on the form without snagging the fabric. The treatmentshould not be ofsuch kind ;as might raise points on ,the surface as such projections would injure .the fabric. The ,desired frictiQD l .charactershculd be ,pro- .duced, as by .one of the processes above set forth, to provide a multiplicity of minute pittings or small depressions therein so that the knitted loops .of thestoeking fabric will cling to the surface. While it" might seem that a surface such ,as described would not have a high frictional characteristic, it has been found hat. the drying form will satisfactorily hold a stocking against creeping ,or shrinking if substantially the whole surface thereof which contacts the stocking is treated according .to the invention. It is,

however, not necessary that the complete surface of the form be treated as described to attain the desired result. Thus, for

,example, ,there is little danger of creeping ,ofthe fabricon the foot portion because the stocking foot is maintained in proper position due to the curvature of the of the form form in such areas and, hence, a, friction surface is not required in this portion.

. It willalso be readily apparent that a surface .of this character, being rough and .dull, as compared to the smooth polished surfaces heretofore in use, will materially improve the heat radiating properties of .the form and thus improve the drying operation.

A surface such as that described has been found, in actual .practice, to accomplish the results heretofore pointed out, namely, the secure retaining of thestocking on the form and the prevention of creeping. As is well known in the art, when stockings are boarded they are pulled. down upon the form to a certain point and when the fabric dries and sets, the stocking creeps upward on the form so that it is ultimately of less length than it was when originally pulled down on the form. With a form having a surface such as herein described, it has been found that there is practically no creeping of the stocking and hence, longer lengths are obtainable by the use of the forms having a surface in accordance with our invention. That is to-say, if a stocking is pulled down on our form to a predetermined point thereon, it will remain substantially at that point during-the drying operation and hence it is possible accurately to predetermine the length of the finished stocking. In certain tests conducted, it was found that forms havinga surface of our invention produced two and a half times as many stockings of 30 inch lengthas were producedoni forms having a smooth, polished finish, and more than fourtimes as many stockings of 31 inch length as were producedon the smooth ,fin- .ished, polished forms. The importance of this result will readily be appreciated When the present high cost of silk .is considered and whenitis realized that the manufactursmooth finish. As above ,pointed out, this result could not be obtained .bythe use ,of fabric clamps which are apt .to injur ,the

delicate fabric .ofthe sheer ,chiffon hosiery now be ng manufactured and furthermore such clamps ,are apt ,to leave ,marks .on .the finished stocking which .may render them unfit for the trade.

It is believed that the foregoing descrip tion of the finish of our form and the method of proc'lueing the same will be entirely Clear. By reference .to its appearance, it may be stated that the surface which we produce on hosiery d rying forms resembles, somewhat, the surface of an egg she'll and hence we have designated our forms having this finish as egg shell .fi'nish forms; It will be understood, of course, that this type of finish is entirely independent of the construction of the form and that .ourinvention is in no way limited to a. form ,of any particular construction. That is to say,ou{r invention is not confined .toj thelsurface of a form of sheet metal havingsideswhich are welded together, but may'also be embodied in cast metal forms of hard metal which can be successfully sand-blasted and forms of similar materials no matter what may be their particular mode of assembly or construction.
